Chủ đề: Presence Attestation — the Birth of Trust On Your Device
Abstract: Many popular modern processors include an important hardware security feature in the form of a DRTM (Dynamic Root of Trust for Measurement) that helps bootstrap trust and resists software attacks.
However, despite substantial body of prior research on trust establishment, security of DRTM was treated without involvement of the human user, who represents a vital missing link. The basic challenge is: how can a human user determine whether an expected DRTM is currently active on her device?
In this talk, we define the notion of “presence attestation” based on mandatory, though minimal, user participation. We present three concrete presence attestation schemes: sight-based, location-based and scene-based. They vary in terms of security and usability features, and are suitable for different application contexts.
Xuhua Ding is currently an Associate Professor at the Singapore Management University. He received his Ph.D. degree in Computer Science from the University of Southern California in 2003. After working on applied cryptography for more than ten years, his recent research has been shifted to building trustworthy systems for mobile devices and cloud computing. He has published over sixty papers in major security conferences and journals including ACM CCS, USENIX Security, NDSS, ACM TOPS and TODS. He has served on the technical program committees in various international conferences, including ACM CCS 2017.
